ASSEMBH (BS2000/OSD)

Assembler for creating programs in machine code for the /390 architecture.

Current version: V1.3

Assembler is a compiler for converting source code of the identically named symbolic programming language into corresponding machine code. Assembler programs are general-purpose utilities for deployment in all areas of data processing.

Since Assembler is machine-specific by nature (an Assembler language instruction corresponds to each machine instruction), the technical capabilities of the particular CPU involved can be exploited to the maximum extent.

ASSEMBH is a special Assembler language developed for the instruction set of Fujitsu Siemens business servers with /390 architecture. It supports the XS and ESA instruction sets. As Assembler programs can be interfaced with high-level programming languages, these special features can also be accessed from within other languages. Use of the operating system interfaces is enabled via the macro library of the respective BS2000/OSD operating system version.
